Nasal Dilator Devices

Description

TECHNICAL FIELD

Described embodiments generally relate to nasal dilator devices for facilitating respiration. Some embodiments relate to nasal dilator devices to be fitted to the nose to facilitate or improve respiration during sleeping and/or sporting activities and/or for general day-to-day wear. Some embodiments relate to nasal dilator devices including filtration mechanisms to filter airflow during respiration and other embodiments relate to nasal dilator devices including agent delivery mechanisms for delivery of fragrances and/medicaments to the nose during respiration.

BACKGROUND

Nasal dilator devices are worn by users to dilate their nasal cavities when sleeping and/or partaking in sporting activities to thereby facilitate respiration. However, many nasal dilator devices are uncomfortable to wear and/or become easily dislodged from a user's nose during such activities.

In particular, activities that are percussive, such as running, cause nasal dilator devices to move from their position as intended by the user requiring readjustment. In the field of professional sports, such adjustments are a physical and mental distraction that can negate any other intended benefit of such devices.

It is desired to address or ameliorate one or more shortcomings of prior nasal dilator devices, or to at least provide a useful alternative thereto.

Throughout this specification the word “comprise”, or variations such as “comprises” or “comprising”, will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps.

Any discussion of documents, acts, materials, devices, articles or the like which has been included in the present specification is not to be taken as an admission that any or all of these matters form part of the prior art base or were common general knowledge in the field relevant to the present disclosure as it existed before the priority date of each claim of this application.

DESCRIPTION OF EMBODIMENTS

Referring to FIG. 1A to 1E, there is illustrated a nasal dilator device, generally indicated at 100 and substantially symmetrical about a longitudinal axis L, according to some embodiments. The nasal dilator device 100 comprises a generally U-shaped body 102 having a central portion 104 and first and second leg members, 106a and 106b, respectively, extending from the central portion 104 in a first plane P1.

The nasal dilator device comprises a first intermediate section 108a extending from an end 107a of the first leg member 106a and a second intermediate section 108b extending from an end 107b of the second leg member 106b. In some embodiments, and as depicted in FIGS. 1A to 1E, the first and second intermediate portions 108a, 108b, may be curved or arcuate along their length. In other embodiments, the first and second intermediate portions 108a, 108b may be substantially straight along their length or may comprise a plurality of angled or arcuate portions. The first and second intermediate portions 108a, 108b may extend obtusely from the first plane P1. For example, the first and second intermediate portions 108a, 108b may extend obtusely from the first and second ends 107a, 107b, for example, substantially at an angle of between approximately 95° and 130° to the longitudinal axis. For example, the first and intermediate sections 108a, 108b may deviate by approximately 100° from the longitudinal axis.

Referring again to FIGS. 1A to 1E, the nasal dilator device 100 comprises a first rib member 110a projecting from the first intermediate section 108a in a second plane P2 and a second rib member 110b projecting from the second intermediate section 108b in a third plane P3. In some embodiments, the first and second rib members 110a, 110b may project substantially outward or laterally of the longitudinal axis of the U-shaped body 102. For example, the first and second rib members 110a, 110b may be cantilever rib members that extend from the first and second intermediate sections 108a, 108b, respectively outwardly from the longitudinal axis and away from one another in a substantially cantilever manner. In some embodiments, the first and second rib members 110a, 110b may be arcuate rib members 110a, 110b or arcuate cantilever rib members 110a, 110b.

In some embodiments, the first and second rib members 110a, 110b may exhibit an elongate arched or bow-like profile which may approximate at least a portion of a circle, ellipse or parabola. For example, the first and second rib members 110a, 110b may extend arcuately along the second and third planes, P2 and P3, respectively in a direction substantially toward the first plane P1.

The first and second rib members 110a, 110b may be flexible and resiliently biased away from the first and second intermediate sections 108a, 108b, respectively, to allow the first and second rib members 110a, 110b to be compressed for insertion into the nose of a user and to reform once placed inside the nose to thereby dilate the nostrils as discussed in more detail below with reference to FIGS. 3A and 3B. As best depicted in FIGS. 1A and 1B, the first intermediate section 108a may extend or transition between the first plane P1 and the second plane P2 to interconnect the end 107a of the first leg member 106a to a proximal end 109a of the first rib member 110a and the second intermediate section 108b may extend or transition between the first plane and the third plane to interconnect the end 107b of the second leg member 106b to a proximal end 109b of the second rib member 110b.

In some embodiments, the configuration of the first and second intermediate sections 108a, 108b may be associated with an orientation or location of the first and second rib members 110a, 110b with respect to the U-shaped body 104. For example, the configuration of the first and second intermediate sections 108a, 108b may dictate or define an angle between the first plane P1 and the second plane P2 and between the first plane P1 and the third plane P3, respectively. The second and third planes, P2 and P3, may each form an acute angle, a right angle, or substantially right angle or an obtuse angle with the first plane P1. For example, the second and third planes P2 and P3, may be converging planes and may each form an obtuse angle of approximately 95° to 130° with the first plane P1 such that the first and second intermediate sections 108a 108b take the form of obtuse arcuate sections. In some embodiments, the first, second and third planes, P1, P2, P3 may be different from each other and in some embodiments, the second and third planes, P2, P3 may be the same plane and may be different to the first plane P1.

In some embodiments, such an overmould material may be provided on at least a portion of the rib members 110a, 110, and/or on at least a portion of the intermediate sections 108a, 108b.

The nasal dilator device 100, 200 may be configured to be orientated in a manner such that the first and second nostril engaging elements 112a, 112b may be positioned at a junction of the greater alar cartilage and lateral nasal cartilage, providing improved support for dilation of the nasal passage 308, as discussed in more detail with reference to FIGS. 3A and 3B below.

FIG. 3A is a perspective view of a user, generally indicated at 300, wearing or donning the nasal dilator device 100 of FIG. 1A and FIG. 3B is a cross sectional view taken along a midline A-A of the nose of the user of FIG. 3A.

As depicted in FIGS. 3A and 3B, the nasal dilator device 100 is configured to be orientated such that the central portion 104 spans a septum 302, and in particular, a columella 310 (the terminal section or fleshy external end of the septum) of a nose 304 and is positioned toward a tip 306 of the nose 304 and the first and second leg members 106a, 106b extend inward, along a nasal passage 308. For example, the first and second leg members 106a, 106b, may extend inward at an angle of approximately 30 to 40 degrees to a midline A-A of the nose 304. The first and second intermediate sections 108a, 108b may extend along a length of the septum 302 behind the columella 310 and the fibrofatty tissue 305 or bulbous region around the base of the nostrils 314 and the first and second rib members 110a, 110b, each may extend from a floor 312 of the nasal passage 308 behind the columella 310 and the fibrofatty tissue 305 or bulbous region around the base of the nostrils 314 to an inner wall (not shown) of the nostrils 314. In this way, the nasal dilator device 100 may be securely retained within the nose 304 with little or no pinching of or pressure being exerted on the septum 302. Furthermore, the ergonomic shape of the intermediate portions 108a, 108b allows the nasal dilator device to sit within the nose in a manner that may accommodate various shapes and sizes of noses, including those having hanging columellas 310.

In some embodiments, the first and second rib members 110a, 110b of the nasal dilator device 100 are composed of a flexible material and are generally squeezed or compressed by a user into a compressed state to allow insertion into the nasal passages 308 of the nose 304. The first and second rib members 110a, 110b may be biased to reform or revert to a natural uncompressed state and once inserted into the nasal passage 308, the first and second rib members 110a, 110b may each exert an outward force on the inner wall (not shown) of the nostril 314 and on the floor 312 of the nose 304, to thereby dilate the nasal passage 308. Thus, as opposed to exerting pressure on the septum 302 to dilate the nasal passage 308, the intermediate portions 108a, 108b, of nasal dilator device 100 are effective to cause the first and second rib members 110a, 110b to use the floor 312 of the nose 304 as a support structure for dilation of the nostrils 314. By using the floor 312 of the nose 304 as a support structure or anchor from which the first and second rib members 110a, 110b may launch or push off from, any pinching or exertion of force on the septum may be mitigated or avoided and a more comfortable and natural or anatomical fit may be achieved.

The nasal dilator device 100 is configured to cooperate with internal contours of the nose 304 and sit securely and comfortably in the nose, whilst mitigating obstruction of air flow through the nasal passage 308. For example, the rib members 110a, 110b, may be curved or arcuate along their length to correspond with the internal contours of the nose 304 and provide a more comfortable fit. In some embodiments, the first and second leg members 106a, 106b may be inclined toward each other or converge such that a relatively greater distance is provided between the first and second leg members 106a, 106b towards the central portion 104 in order to accommodate the columella 310 and to assist in holding the nasal dilator device 100 in place when worn.

Referring now to FIGS. 4A to 4D, there is illustrated a nasal dilator device, generally indicated at 400, according to some embodiments. The nasal dilator device 400 may comprise similar components and elements to those of nasal dilator device 100 depicted in FIGS. 1A to 1E and accordingly those similar components and elements are denoted like numerals.

In addition to those similar components and elements of nasal dilator device 100, nasal dilator device 400 may comprise a first and second releasable attachment mechanism 402a and 402b, respectively. The first and second releasable attachment mechanism 402a, 402b may comprise mating or interlocking components and may be employed to releasably attach the first and second rib members, 110a and 110b, respectively, to the U-shaped body 102, to thereby define first and second adjustable looped structures, 411a, and 411b, respectively.

In some embodiments, the first and second releasable attachment mechanisms 402a, 402b may comprise respective arms 404a, 404b, such as pins, extending from respective reverse or inner surfaces 406a, 406b of the first and second nostril engaging elements 112a, 112b. The first and second releasable attachment mechanisms 402a, 402b may comprise respective sockets 408a, 408b for receiving and/or engaging the respective arms 404a, 404b. The first and second releasable attachment mechanisms 402a, 402b may be configured to allow a user to selectively adjust a degree of dilation or expansion and contraction of the first and second rib members 110a and 110b with respect to the U-shaped body 102.

For example, and as best illustrated in FIGS. 4C and 4D, the arms 404a, 404b may include at least one of or a series of serrations, detents or protrusions 410 arranged to engage with at least one of or a series of grooves or ridges 412 provided on or within the sockets 408a, 408b. For example, the grooves or ridges 412 may extend downwardly from a upper jaw portion 414 of the sockets 408a, 408b and/or may extend upwardly from a lower jaw portion 416.

Application of sufficient force by a user to the first and second releasable attachment mechanisms 402a, 402b may be effective to move the arms 404a, 404b with respect to the sockets 408a, 408b and overcome a restrictive force between the detents 410 and the grooves 412 to allow the detents 410 and/or the grooves 412 to deform and the degree or level of dilation to be adjusted. The engagement of the detents 410 with the grooves 412 may provide a sufficient restrictive force to hold the arms 404a, 404b fixed when provided in the nose 304, as depicted in FIG. 5.

The arms 404a, 404b may comprise stoppers 414 at their ends to prevent or hinder the arms 404a, 404b from disengaging from or withdrawing from the respective sockets 408a, 408b. For example, application of a relatively large pulling force may be sufficient to cause the arms 404a, 404b to withdraw from the sockets 408a, 408b. In some embodiments, the stoppers 414 may be arrow shaped.

In some embodiments, the sockets 408a, 408b may be disposed on the first and second intermediate sections 108a, 108b and extend therefrom towards the respective arms 404a, 404b. The releasable attachment mechanisms 402a, 402b may be arranged to releasably attach or lock the first and second nostril engaging elements 112a, 112b to the first and second intermediate sections 108a, 108b.

In other embodiments, the sockets 408a, 408b may be disposed on the first and second leg members 106a, 106b and extend therefrom towards the respective arms 404a, 404b. The releasable attachment mechanisms 402a, 402b may be arranged to releasably attach or lock the first and second nostril engaging elements 112a, 112b to the first and second leg members 106a, 106b.

In other embodiments, the sockets 408a, 408b may be disposed on the first and second rib members 110a, 110b and extend therefrom towards the respective arms 404a, 404b. The attachment mechanisms 402a, 402b may be arranged to releasably attach or lock the first and second nostril engaging elements 112a, 112b to the first and second rib members 110a, 110b.

In other embodiments, the first and second releasable attachment mechanisms 402a, 402b may comprise respective sockets 408a, 408b, extending from the respective reverse or inner surfaces 406a, 406b, of the first and second nostril engaging elements 112a, 112b and respective arms 404a, 404b extending from the first and second intermediate sections 108a, 108b, the first and second leg members 106a, 106b, or the first and second rib members 110a, 110b.

As illustrated in FIG. 4C, the arms 404a, 404b may be fully or substantially fully inserted into the respective sockets 408a, 408b to enable the nasal dilator device 400 to adopt or assume a fully closed or substantially fully closed state, to thereby tighten or contract the looped structures 411a, 411b.

As illustrated in FIG. 4D, the arms 404a, 404b may be partially inserted into the sockets 408a, 408b to enable the nasal dilator device 400 to adopt or assume a partially closed state, to provide for looser or less tight looped structures 411a, 411b and accommodate variations in nasal passage sizes.

The nasal dilator device 600 may comprise similar components and elements to those of nasal dilator device 400 depicted in FIGS. 4A to 4D and accordingly those similar components and elements are denoted like numerals.

The nasal dilator device 600 comprises at least one capsule 602 disposed within respective sockets 408a, 408b. The capsule 602 may include an agent such as a medicament and/or a fragrance or aromatic agent. As depicted in FIG. 6B, the arms 404a, 404b are configured to activate, pierce or burst the capsules 602 to release the agent, medicament and/or fragrance or aromatic agent when inserted into the sockets 408a, 408b. In this way, the medicament and/or fragrance or aromatic agent is released only when the capsule 602 is activated, pierced or burst, thereby increasing a longevity or “shelf-life” and/or protecting the integrity of the medicament and/or aromatic agent. For example, the agent may be an aromatic scent such as an essential oil blend or synthetic fragrance blend to provide an olfactory and/or physiological response such as decongesting the nasal passages 318, promoting relaxation, promoting sleepiness, suppressing appetite or a medicament such as a drug to reduce pain such as a migraine.

The pads 118a, 118b may be composed of a relatively soft overmould material, for example, a polymer material such as thermoplastic elastomer (TPE). In some embodiments, the pads 118a, 118b may be configured to cooperate with and conform to the surface area 116a, 116b and the series of protrusions 1102 such that the overmoulded series of protrusions 1102 project or protrude from the overmoulded surface area 116a, 116b. In other embodiments, the surface areas 116a, 116b of the nostril engaging members 114a, 114b may be substantially smooth or flat and the pads 118a, 118b may comprise or form the series of protrusions 1102. For example, the pads 118a, 118b may be substantially elongate, for example, extending from the distal ends 114a, 114b of the rib members 110a, 110b, and the protrusions 1102 may extend along a length of the pads 118a, 118b.

In some embodiments, an overmould material may be provided on at least a portion of the rib members 110a, 110b, on at least a portion of the intermediate sections 108a, 108b, and/or on at least a portion of the u-shaped body 102. For example, the overmould may be configured to cooperate with and conform to the major surface 1106 of the nasal dilator device 1100 and the one or more projections 1104 such that the overmoulded projections 1104 project or protrude from the overmoulded major surface 1106. In other embodiments, the major surface 1106 of the nasal dilator device 1100 may be substantially smooth or flat and an overmould disposed thereon may comprise or form the one or more projections or ridges 1104.

The series of protrusions 1102 and/or the one or more projections 1104 may provide a comfortable and/or grippable surface for engaging with the inner walls of the nose in use. The series of protrusions 1102 and/or the one or more projections 1104 may provide for or create a drag effect which may improve retention of the nasal dilator device 1100 in a desired position in a user's nose, in use, despite movement or motion of the user.

Referring now to FIGS. 12A, 12B and 12C, there is illustrated a nasal dilator device, generally indicated at 1200, according to some embodiments. The nasal dilator device 1200 may comprise similar components and elements to those of nasal dilator device 1100 depicted in FIG. 11 and accordingly those similar components and elements are denoted like numerals.

In addition to those similar components and elements of nasal dilator device 1100, nasal dilator device 1200 may comprise a first and second releasable attachment mechanism 1202a and 1202b, respectively. The first and second releasable attachment mechanism 1202a, 1202b may comprise mating or interlocking components and may be employed to releasably attach the first and second rib members, 110a and 110b, respectively, to the U-shaped body 102, to thereby define first and second adjustable looped structures, 1204a, and 1204b, respectively. The first and second releasable attachment mechanisms 1202a, 1202b may allow a user to selectively adjust a degree of dilation or expansion and contraction of the first and second rib members 110a and 110b with respect to the U-shaped body 102.

The first and second releasable attachment mechanisms 1202a, 1202b may comprise respective arms 1206a, 1206b, such as pins, and respective sockets 1208a, 1208b for receiving and/or engaging the respective arms 1206a, 1206b.

As illustrated in FIGS. 12A, 12B and 12C, the arms 1206a, 1206b may be disposed on and extend from respective first and second intermediate sections 108a, 108b toward respective sockets 1208a, 1208b provided on opposite or inner surfaces 1210a, 1210b of the first and second nostril engaging elements 112a, 112b. In some embodiments, as shown in FIGS. 12A and 12C, the first and second arms 1206a, 1206b extend from respective first and second arm supports 1207a, 1207b projecting from respective first and second intermediate sections 108a, 108b. The releasable attachment mechanisms 1202a, 1202b may therefore be arranged to releasably attach or lock the first and second nostril engaging elements 112a, 112b to the first and second intermediate sections 108a, 108b.

In other embodiments, the first and second arms 1206a, 1206b may be disposed on and extend from respective first and second rib members 110a, 110b toward respective first and second sockets 1208a, 1208b to allow the releasable attachment mechanisms 1202a, 1202b to releasably attach or lock the first and second nostril engaging elements 112a, 112b to the first and second rib members 110a, 110b or the first and second arms 1206a, 1206b may be disposed on and extend from respective first and second leg members 106a, 106b toward respective first and second sockets 1208a, 1208b to allow the releasable attachment mechanisms 1202a, 1202b to releasably attach or lock the first and second nostril engaging elements 112a, 112b to the first and second leg members 106a, 106b.

In other embodiments, the first and second releasable attachment mechanisms 1202a, 1202b may comprise first and second arms 1206a, 1206b extending from the respective opposite or inner surfaces 1210a, 1210b of the first and second nostril engaging elements 112a, 112b and first and second sockets 1208a, 1208b extending from the first and second intermediate sections 108a, 108b, the first and second rib members 110a, 110b, or the first and second leg members 106a, 106b.

Referring again to FIGS. 12A,12B and 12C, the first and second arms 1206a, 1206b may include at least one or a series of serrations, detents or protrusions 1212 arranged to engage with at least one or a series of grooves or ridges 1214 provided on or within the sockets 1208a, 1208b. For example, the grooves or ridges 1214 may extend downwardly from a upper jaw portion 1216 of the sockets 1208a, 1208b and/or may extend upwardly from a lower jaw portion 1218.

Application of sufficient force by a user to the first and second releasable attachment mechanisms 1202a, 1202b may be effective to move the arms 1206a, 1206b with respect to the sockets 1208a, 1208b and overcome a restrictive force between the detents 1212 and the grooves 1214 to allow the detents 1212 and/or the grooves 1214 to deform and the degree or level of dilation to be adjusted. The engagement of the detents 1212 with the grooves 1214 may provide a sufficient restrictive force to hold the arms 1206a, 1206b fixed when provided in a user's nose.

As depicted in FIG. 12, the arms 1206a, 1206b may each comprise a stopper or catch 1220 provided at their free ends to prevent or hinder the arms 1206a, 1206b from disengaging from or withdrawing from the respective sockets 1208a, 1208b. For example, in some embodiments, the catch 1220 comprises a hook portion 1222 which is configured to cooperate with a corresponding notch 1224 disposed in an upper or lower jaw portion 1216, 1218 of the socket. Application of a relatively large pulling force may be sufficient to cause the catch 1220 to disengage with the notch 1224 and to cause the arms 1206a, 1206b to withdraw from the sockets 1208a, 1208b.

In some embodiments, as best shown in FIGS. 12A and 12C, the sockets 1208a, 1208b may take the form of substantially elongate housings 1226 provided with apertures 1228 or gaps in side walls of the housing 1226. The housings 1226 may be substantially wedge shaped and taper along their length towards opposite or inner surfaces 1210a, 1210b, of the first and second nostril engaging elements 112a, 112b to provide a relatively broad opening to receive the arms 1206a, 1206b. The elongate or wedge shaped housing 1226 may provide for an improved engagement between the arms 1206a, 1206b and sockets 1208a, 1208b and more robust releasable attachment mechanisms 1202a, 1202b. For example, the elongate or wedge shaped housing 1226 may allow a face 1230 of the socket housing to engage with and lie substantially flush with the arm supports 1207a, 1207b, the intermediate sections 108a, 108b, rib members 110a, 110b, or leg members 106a, 106b, when the arms 1206a, 1206b are fully engaged within the sockets 1208a, 1208b, when the nasal dilator device 1200 assumes a closed state. For example, in use, such a configuration may mitigate contact between the sockets 1208a, 1208b and the septum and relative movement or twisting of the sockets as a result of contact with the septum. The elongate or wedge shaped housing 1226 may facilitate improved or easier adjustment of the first and second releasable attachment mechanisms 1202a, 1202b.

The arms 1206a, 1206b may be fully or substantially fully inserted into the respective sockets 1208a, 1208b to enable the nasal dilator device 1200 to adopt or assume a fully closed or substantially fully closed state, to thereby tighten or contract the looped structures 1211a, 1211b. The arms 1206a, 1206b may be partially inserted into the sockets 1208a, 1208b to enable the nasal dilator device 1200 to adopt or assume a partially closed state, to provide for looser or less tight looped structures 1204a, 1204b and accommodate variations in nasal passage sizes.

As depicted in FIGS. 12A, 12B, and 12C, the nasal dilator device 1200 may include a series of protrusions 1102 disposed on the nostril engaging members 112a, 112b, and/or one or more projections 1104 protruding from the major surface 1106 of the nasal dilator device 1200, as discussed with reference to FIG. 11.

Similar to the embodiment of nasal dilator device 600 depicted in FIG. 6, in some embodiments, the nasal dilator device 1200 may comprise at least one capsule (not shown), which may include an agent such as a medicament and/or a fragrance or aromatic agent, disposed within respective sockets 1208a, 1208b. The arms 1206a, 1206b may be configured to activate, pierce or burst the capsule (not shown) to release the agent, medicament and/or fragrance or aromatic agent when they are inserted into the sockets 1208a, 1208b. In this way, the medicament and/or fragrance or aromatic agent is released only when the capsule (not shown) is activated, pierced or burst, thereby increasing a longevity or “shelf-life” and/or protecting the integrity of the medicament and/or aromatic agent.

Similar to the embodiment of nasal dilator device 700 depicted in FIG. 7, in some embodiments, the nasal dilator device 1200 may comprise at least one coating or film (not shown) arranged to release a fragrance, aroma or medicament. For example, the film (not shown) may be disposed on a surface of at least one of the attachment mechanisms 1202a, 1202b, such as on an inner surface of the looped structures 1204a, 1204b, on the central portion 102, on the first and second leg members 106a, 106b, on the first and second intermediate sections 108a, 108b, on the rib members 110a, 110b, and/or on the first and second nostril engaging elements 112a, 112b.

In some embodiments, the film (not shown) is arranged to release a fragrance, aroma or medicament in response to abrasion, such as scratching, scraping and may be provided with an outer cover, seal or strip to protect the film (not shown) from unintended abrasion. In other embodiments, the coating or film (not shown) may be arranged to release a fragrance, aroma or medicament in response to the removal or peeling off of an outer cover, strip or seal. In some embodiments, a fragrance, aroma or medicament may be provided or retained between two strips or films (not shown) forming a blister. For example, the coating or film (not shown) may comprise a polymer or a fibre and/or may be in the form of a “scratch and sniff” technology or peel off technology.

Referring to FIGS. 13A and 13B, there is illustrated a nasal dilator device, generally indicated at 1300. The nasal dilator device 1300 is substantially symmetrical about a longitudinal axis L, according to some embodiments, and comprises a generally U-shaped body 1302 having a central portion 1304 and first and second leg members, 1306a and 1306b, respectively, extending from the central portion 1304 in a first plane P1.

The nasal dilator device comprises a first intermediate section 1308a extending from an end 1307a of the first leg member 1306a and a second intermediate section 1308b extending from an end 1307b of the second leg member 1306b. In some embodiments, and as depicted in FIGS. 13A and 13B, the first and second intermediate portions 1308a, 1308b, may be angled, curved or arcuate along their length and/or may comprise a plurality of angled or arcuate portions. In some embodiments, the first and second intermediate portions 108a, 108b may comprise L-shaped or right angled sections. For example, the first and second intermediate portions 108a, 108b may extend from the first and second ends 107a, 107b in a substantially perpendicular direction to the longitudinal axis L to form substantially right angled intermediate portions.

The nasal dilator device 1300 comprises a first rib member 1310a projecting from the first intermediate section in a second plane P2 and a second rib member 1310b projecting from the second intermediate section 1308b in a third plane P3. For example, and as best depicted in FIG. 13A, the first intermediate section 1308a may connect the end 1307a of the first leg member 1306a to a proximal end 1309a of the first rib member 1310a and the second intermediate section 1308b may connect the end 1307b of the second leg member 1306b to a proximal end 1309b of the second rib member 110b. In some embodiments, the first intermediate section 1308a extends from the first plane P1 to the second plane P2 and the second intermediate section 1308b extends from the first plane P1 to the third plane P3.

In some embodiments, the first and second rib members 1310a, 1310b may project substantially outward or laterally of the longitudinal axis of the U-shaped body 1302. For example, the first and second rib members 1310a, 1310b may be cantilever rib members that extend from the first and second intermediate sections 1308a, 1308b, respectively outwardly from the longitudinal axis and away from one another in a substantially cantilever manner. In some embodiments, the first and second rib members 1310a, 1310b may be arcuate rib members 1310a, 1310b or arcuate cantilever rib members 1310a, 1310b.

In some embodiments, the first and second rib members 1310a, 1310b may exhibit an elongate arched or bow-like profile which may approximate at least a portion of a circle, ellipse or parabola. For example, the first and second rib members 1310a, 1310b may extend arcuately along the second and third planes, P2 and P3, respectively in a direction substantially toward the first plane P1.

The first and second rib members 1310a, 1310b may be flexible and resiliently biased away from the first and second intermediate sections 1308a, 1308b respectively, to allow the first and second rib members 1310a, 1310b to be compressed for insertion into the nose of a user and to reform once placed inside the nose to thereby dilate the nostrils.

In some embodiments, the configuration of the first and second intermediate sections 1308a, 1308b may be associated with an orientation, positioning or location of the first and second rib members 1310a, 1310b with respect to the U-shaped body 1302. For example, the configuration of the first and second intermediate sections 1308a, 1308b may dictate or define a relationship or an angle between the first plane P1 and the second plane P2 and between the first plane P1 and the third plane P3, respectively. The second and third planes, P2 and P3, may each form an acute angle, a right angle, or substantially right angle or an obtuse angle with the first plane P1.

For example, in some embodiments, the first and second intermediate sections 1308a 1308b may take the form of substantially right angled sections such that the second and third planes P2, P3 each form a right angle with the first plane P1. In other embodiments, the first and second intermediate sections 1308a 1308b may take the form of obtuse angled or arcuate sections such that the second and third planes P2 and P3, each form an obtuse angle with the first plane P1. In other embodiments, the first and second intermediate sections 1308a 1308b may take the form of acute angled or arcuate sections such that the second and third planes P2 and P3, each form an acute angle with the first plane P1.

In some embodiments, the second and third planes P2 and P3, may be converging planes such that the first and second cantilever rib members are angled and/or extend substantially toward the central portion of the U-shaped body. In other embodiments, the second and third planes are diverging planes such that the first and second cantilever rib members are angled and/or extend substantially toward the central portion of the U-shaped body.

In some embodiments, the first, second and third planes, P1, P2, P3 may be different from each other and in some embodiments, the second and third planes, P2, P3 may be the same plane and may be different to the first plane P1. In some embodiments, the first and second planes P1, P2 may be orthogonal to the first plane P1.

For example, in some embodiments, the nasal dilator device 1300 is configured to be orientated such that, in use, the central portion 1304 spans a septum 302, and in particular, a columella (the terminal section or fleshy external end of the septum) of a nose and is positioned toward a tip of the nose and the first and second leg members 1306a, 1306b extend inward of respective nasal orifices, along a nasal passage and/or the septum of the nose. The first and second leg members 1306a, 1306b, may extend inward at an angle of approximately 30 to 40 degrees to a midline of the nose. The first and second intermediate sections 1308a, 1308b may engage with the septum and extend from the septum behind the columella and alar fibrofatty tissue or bulbous region around the base of the nostrils of the nose allowing the first and second rib members, in use, to extend along the respective nasal orifices to an inner wall of the nostrils behind the columella and the fibrofatty tissue or bulbous region around the base of the nostrils to an inner wall of the nostrils. In this way, the nasal dilator device 1300 may be securely retained within the nose with little or no pinching of or pressure being exerted on the septum.

The first and second intermediate sections 1308a, 1308b may be inclined away from or diverge from one another to assist in urging the respective first and second rib members 1310a, 1310b against inner walls of respective nostrils when worn by the user.

As depicted in FIGS. 13A and 13B, the first and second rib members 1310a, 1310b, of the nasal dilator device 1300 may comprise respective first and second nostril engaging elements, 1312a and 1312b, disposed at distal ends 1314a, 1314b, of the first and second arcuate rib members 1310a, 1310b, respectively, for engaging with inner walls of respective nostrils when worn by a user. In some embodiments, the first and second nostril engaging elements, 1312a, 1312b may comprise relatively large surface areas 1316a, 1316b with respect to the first and second arcuate rib members 1310a, 1310b.

In some embodiments, the first and second nostril engaging elements, 1312a, 1312b, may extend at an angle to or arcuately from the respective first and second distal ends 1314a, 1314b, of the respective first and second rib members 1310a, 1310b. For example, the first and second nostril engaging elements, 1312a, 1312b, may extend from the first and second planes, P2, P3, respectively and may extend in a direction away from the central portion 104 of the U-shaped body 1302.

In some embodiments, the first and second nostril engaging elements 1312a, 1312b may have pads 1318a, 1318b, disposed thereon, to engage with the inner walls of the nostrils of a user, in use. For example, the pads 1318a, 1318b may be disposed on the relatively large major surface areas 1316a, 1316b of the nostril engaging elements, 1312a and 1312b and may be enlarged with respect to the first and second arcuate rib members 1310a, 1310b, and/or the nostril engaging elements, 1312a, 1312b. The pads 1318a, 1318b of the nasal dilator device 1300 may be composed of a relatively soft overmould material, for example a polymer material such as thermoplastic elastomer (TPE) to provide a comfortable and/or grippable surface for engaging with the inner walls of the nostrils in use.

In some embodiments, as depicted in FIGS. 13A and 13B, the relatively large surface areas 1316a, 1316b of the nostril engaging members 1312a, 1312b are provided with a series of protrusions 1320. The nostril engaging members 1312a, 1312b may be substantially elongate, for example, extending from the distal ends 1314a, 1314b of the rib members 1310a, 1310b, and the protrusions 1320 may extend along a length of the surface areas 1316a, 1316b of the nostril engaging members 1312a, 1312b. In some embodiments, the surface areas 1316a, 1316b of the nostril engaging members 1312a, 1312b may be substantially oval, rectangular, triangular or truncated triangular in shape. In some embodiments, the series of protrusions 1320 may form a u-shaped pattern, a v-shaped pattern, or elongated v or ✓ (tick) shaped pattern, such as a chevron design, comprising a plurality of aligned u-shaped, v-shaped or elongated v or ✓ (tick) shaped protrusions 1320.

As depicted in FIGS. 13A and 13B, the rib members 1310a, 1310b of the nasal dilator device 1300 may comprise one or more projections 1304, flanges or ridges protruding from a major surface 1324 of the nasal dilator device 1300 and extending along at least a portion of a length of the rib members 1310a, 1310b. For example, the major surface 1324 of the nasal dilator device 1300 may be the surface of the nasal dilator device 1300 configured, in use, to engage with or face nasal passage walls of a user's nose. In some embodiments, as depicted in FIGS. 13A and 13B, the nasal dilator device 1300 may comprise first and second projections 1322, each forming a flange disposed at respective elongate edges of the major surface 1324 of the nasal dilator device 1300.

The one or more projections 1322 may extend from the distal ends 1314a, 1314b of the rib members 1310a, 1310b toward the intermediate sections 1308a, 1308b. For example, as depicted in FIG. 13A, the one or more projections 1322 may integrate with and extend from corresponding protrusions 1320 of the series of protrusions 1320 provided on the surface areas 1316a, 1316b of the nostril engaging members 1312a, 1312b. In some embodiments, the one or more projections 1322 may be disposed on and project from the major surface 1324 of the intermediate sections 1308a, 1308b and/or the leg members 1306a, 1306b and/or the central portion 1304 of the nasal dilator device 1300.

In some embodiments, the pads 1318a, 1318b may be configured to cooperate with and conform to the surface area 1316a, 1316b and the series of protrusions 1320 such that the overmoulded series of protrusions 1320 project or protrude from the overmoulded surface area 1316a, 1316b. In other embodiments, the surface areas 1316a, 1316b of the nostril engaging members 1314a, 1314b may be substantially smooth or flat and the pads 1318a, 1318b may comprise or form the series of protrusions 1320. For example, the pads 1318a, 1318b may be substantially elongate, for example, extending from the distal ends 1314a, 1314b of the rib members 1310a, 1310b, and the protrusions 1320 may extend along a length of the pads 1318a, 1318b.

In some embodiments, an overmould material may be provided on at least a portion of the rib members 1310a, 1310, on at least a portion of the intermediate sections 1308a, 1308b, and/or on at least a portion of the u-shaped body 1302. For example, the overmould may be configured to cooperate with and conform to the major surface 1322 of the nasal dilator device 1300 and the one or more projections 1322 such that the overmoulded projections 1322 project or protrude from the overmoulded major surface 1324. In other embodiments, the major surface 13024 of the nasal dilator device 1300 may be substantially smooth or flat and an overmould disposed thereon may comprise or form the one or more projections or ridges 1322.

The series of protrusions 1320 and/or the one or more projections 1322 may provide a comfortable and/or grippable surface for engaging with the inner walls of the nose in use. For example, activities that are percussive, such as running, are often associated with the production of skin perspiration which may reduce the mechanical and frictional attachment of other nasal devices to the nasal passage of the user causing the devices to move from a position intended by the user and therefore requiring readjustment. However, the series of protrusions 1320 and/or the one or more projections 1322 may provide for or create a drag effect which may improve retention of the nasal dilator device 1300 in a desired position in a user's nose, in use, despite motion or skin perspiration of the user.

Referring now to FIGS. 14A, 14B, 14C, 14D, 14E and 14E, there is illustrated a nasal dilator device, generally indicated at 1400, according to some embodiments. The nasal dilator device 1400 may comprise similar components and elements to those of nasal dilator device 1300 depicted in FIGS. 13A and 13B and accordingly those similar components and elements are denoted like numerals.

In addition to those similar components and elements of nasal dilator device 1300, nasal dilator device 1400 may comprise a first and second releasable attachment mechanism 1402a and 1402b, respectively. The first and second releasable attachment mechanism 1402a, 1402b may comprise mating or interlocking components and may be employed to releasably attach the first and second rib members, 1310a and 1310b, respectively, to the U-shaped body 1302, to thereby define first and second adjustable looped structures, 1404a, and 1404b, respectively. The first and second releasable attachment mechanisms 1402a, 1402b may allow a user to selectively adjust a degree of dilation or expansion and contraction of the first and second rib members 1310a and 1310b with respect to the U-shaped body 1302.

The first and second releasable attachment mechanisms 1402a, 1402b may comprise respective arms 1406a, 1406b, such as pins, and respective sockets 1408a, 1408b for receiving and/or engaging the respective arms 1406a, 1406b.

As illustrated in FIG. 14A to 14F, the arms 1406a, 1406b may be disposed on and extend from respective first and second intermediate sections 1308a, 1308b toward respective sockets 1408a, 1408b provided on opposite or inner surfaces 1410a, 1410b of the first and second nostril engaging elements 1312a, 1312b.

In other embodiments, the first and second arms 1406a, 1406b may be disposed on and extend from respective first and second rib members 1310a, 1310b toward respective first and second sockets 1408a, 1408b to allow the releasable attachment mechanisms 1402a, 1402b to releasably attach or lock the first and second nostril engaging elements 1312a, 1312b to the first and second rib members 1310a, 1310b or the first and second arms 1406a, 1406b may be disposed on and extend from respective first and second leg members 1306a, 1306b toward respective first and second sockets 1408a, 1408b to allow the releasable attachment mechanisms 1402a, 1402b to releasably attach or lock the first and second nostril engaging elements 1312a, 1312b to the first and second leg members 1306a, 1306b.

In other embodiments, as depicted in FIG. 15, nasal dilator device 1500 having first and second releasable attachment mechanisms 1402a, 1402b may comprise first and second arms 1406a, 1406b extending from the respective opposite or inner surfaces 1410a, 1410b of the first and second nostril engaging elements 1312a, 1312b and first and second sockets 1408a, 1408b extending from the first and second intermediate sections 1308a, 1308b. In yet other embodiments, the first and second releasable attachment mechanisms 1402a, 1402b may comprise first and second arms 1406a, 1406b extending from the respective opposite or inner surfaces 1410a, 1410b of the first and second nostril engaging elements 1312a, 1312b and first and second sockets 1408a, 1408b extending from the first and second rib members 1310a, 1310b or the first and second leg members 1306a, 1306b.

Referring again to FIGS. 14A to 14E, the first and second arms 1406a, 1406b may include at least one or a series of serrations, detents or protrusions 1412 arranged to engage with at least one or a series of grooves or ridges 1414 provided on or within the sockets 1408a, 1408b. For example, the grooves or ridges 1414 may extend downwardly from a upper jaw portion 1416 of the sockets 1408a, 1408b and/or may extend upwardly from a lower jaw portion 1418.

Application of sufficient force by a user to the first and second releasable attachment mechanisms 1402a, 1402b may be effective to move the arms 1406a, 1406b with respect to the sockets 1408a, 1408b and overcome a restrictive force between the detents 1412 and the grooves 1414 to allow the detents 1412 and/or the grooves 1414 to deform and the degree or level of dilation to be adjusted. The engagement of the detents 1412 with the grooves 1414 may provide a sufficient restrictive force to hold the arms 1406a, 1406b fixed when provided in a user's nose.

As depicted in FIGS. 14A to 14E, the arms 1406a, 1406b may each comprise a stopper or catch 1420 provided at their free ends to prevent or hinder the arms 1406a, 1406b from disengaging from or withdrawing from the respective sockets 1408a, 1408b. For example, in some embodiments, the catch 1420 comprises a hook portion 1422 which is configured to cooperate with a corresponding notch 1424 disposed in an upper or lower jaw portion 1416, 1418 of the socket 1408a, 1408b. Application of a relatively large pulling force may be sufficient to cause the catch 1420 to disengage with the notch 1424 and to cause the arms 1406a, 1406b to withdraw from the sockets 1408a, 1408b.

In some embodiments, as best shown in FIGS. 14A and 14B, the sockets 1408a, 1408b may take the form of substantially elongate housings 1426 provided with apertures 1428 or gaps in side walls of the housing 1426. The housings 1426 may be substantially wedge shaped and taper along their length towards opposite or inner surfaces 1410a, 1410b, of the first and second nostril engaging elements 1312a, 1312b to provide a relatively broad opening to receive the arms 1406a, 1406b. The elongate or wedge shaped housing 1426 may provide for an improved engagement between the arms 1406a, 1406b and sockets 1408a, 1408b and more robust releasable attachment mechanisms 1402a, 1402b. For example, the elongate or wedge shaped housing 1426 may allow a face 1430 of the socket housing 1426 to engage with and lie substantially flush to the intermediate sections 1308a, 1308b, rib members 1310a, 1310b, or leg members 1306a, 1306b, when the arms 1306a, 1306b are fully engaged within the sockets 1408a, 1408b, when the nasal dilator device 1400 assumes a closed configuration or state.

The arms 1406a, 1406b may be fully or substantially fully inserted into the respective sockets 1408a, 1408b to enable the nasal dilator device 1400 to adopt or assume a fully closed or substantially fully closed state, to thereby tighten or contract the looped structures 1411a, 1411b. The arms 1406a, 1406b may be partially inserted into the sockets 1408a, 1408b to enable the nasal dilator device 1400 to adopt or assume a partially closed state, to provide for looser or less tight looped structures 1404a, 1404b and accommodate variations in nasal passage sizes.

The particular configuration of the releasable attachment mechanisms 1402a, 1402b allows for self-adjustment of the looped structures, 1404a, and 1404b of the nasal dilator device 1400 whilst the device is in place of the nose of the user. This may be of particular benefit to a user partaking in percussive activities. For example, percussive activities, such as running or cycling, may cause a reduction in mechanical and frictional attachment of the nasal dilator device to a nasal passage of a user, for example, due to motion and/or skin perspiration, causing the device to move from a position intended by the user and therefore requiring readjustment.

As depicted in FIGS. 14A to 14F, the nasal dilator device 1400 may include a series of protrusions 1320 disposed on the nostril engaging members 1312a, 1312b, and/or one or more projections 1322 protruding from the major surface 1324 of the nasal dilator device 1400, as discussed with reference to FIG. 13.

Similar to the embodiment of nasal dilator device 600 depicted in FIG. 6, in some embodiments, the nasal dilator device 1400 may comprise at least one capsule (not shown), which may include an agent such as a medicament and/or a fragrance or aromatic agent, disposed within respective sockets 1408a, 1408b. The arms 1406a, 1406b may be configured to activate, pierce or burst the capsule (not shown) to release the agent, medicament and/or fragrance or aromatic agent when they are inserted into the sockets 1408a, 1408b. In this way, the medicament and/or fragrance or aromatic agent is released only when the capsule (not shown) is activated, pierced or burst, thereby increasing a longevity or “shelf-life” and/or protecting the integrity of the medicament and/or aromatic agent.

Similar to the embodiment of nasal dilator device 700 depicted in FIG. 7, in some embodiments, the nasal dilator device 1400 may comprise at least one coating or film (not shown) arranged to release a fragrance, aroma or medicament. For example, the film (not shown) may be disposed on a surface of at least one of the attachment mechanisms 1402a, 1402b, such as on an inner surface of the looped structures 1404a, 1404b, on the central portion 1302, on the first and second leg members 1306a, 1306b, on the first and second intermediate sections 1308a, 1308b, on the rib members 1310a, 1310b, and/or on the first and second nostril engaging elements 1312a, 1312b.

It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the above-described embodiments, without departing from the broad general scope of the present disclosure. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
